I am regular internet user and my computer is always online and connected to the internet. For that I am aware about the hackers and viruses which could attack my computer. For that purpose I have installed the antivirus program and always been updating it regularly since the day I have installed it. The fair thing is that it protect as it is compatible but does not provide more protection than that. So right now I have decided to install another antivirus program to the same computer. Is it any effect to the computer if I install another one? What will happen if I install another one?
